Description

用亍记录信息的方法和设备 A method and apparatus for recording the information using right foot

技术领域 FIELD

本发明总地涉及将信息,特别是数字信息,记录在盘形记录媒体(如光盘或磁盘,在下文中将这些媒体称为"记录盘")上。 The present invention relates generally to information, particularly digital information, recorded on the disc-shaped recording medium (e.g., optical or magnetic disks, such media will be hereinafter referred to as "recording disc") on. 众所周知,这样的记录盘具有多个基本同心的圆形记录轨道。 It is known, such a recording disc having a plurality of substantially circular concentric recording tracks. 这样的记录轨道可以采用单个圆形轨道或一个连续的螺旋形轨道的形式。 Such recording tracks may take a single circular track or in the form of a continuous spiral track. 每一个轨道被划分成逻辑块且每一个逻辑块有一个数据区域用于记录数据。 Each track is divided into logic blocks and each logic block has a data area for recording data. 而且,每一个逻辑块通常保留一个区域用于记录校验数或"检验和,,。 背景技术 Further, each logical block is typically an area reserved for recording the check number or "test and ,, BACKGROUND

一般而言,在一次记录会话中要记录的信息量大于一个逻辑块所能容纳的信息量。 Generally, the amount of information to be recorded in a recording session is greater than the amount of information that can be accommodated in one logical block. 于是要被记录的信息(也被称作"文件")被划分成连续的、具有一个块大小的数据分组,并且一个文件的连续数据分组被记录在盘上的不同逻辑块中。 Thus the information to be recorded (also referred to as "file") is divided into continuous packets having a data block size, and a successive data packets are recorded in different files in a logical block on disc. 对于快速数据传递,则期望将连续的数据分组记录在连续的逻辑块中。 For fast data transfer, it is desirable that the successive data packets recorded in consecutive logical blocks. 于是记录的过程可以实际上连续进行。 And the process can actually recorded continuously. 同样在后来读取(回放)记录在盘上的信息的时间内,读取过程也可以连续进行。 Also in the subsequent reading (playback) time information recorded on the disc, the reading process can also be carried out continuously.

在实践中,盘中可能出现缺陷块,即,在该逻辑块中不再可能无错地记录信息或不再能在读取期间纠正任何所产生的小的写错误。 In practice, a defective block disk may appear, that is no longer possible to record information without error in the logic block or are no longer able to write to correct any small errors generated during reading. 于是这样的逻辑块不再适合于记录信息。 Thus such a logical block is no longer suitable for recording information. 在记录盘中通常会保留一个备用区域,该备用区域不可以被用户寻址并且是用来替换任何缺陷块的。 In the recording disc usually keep a spare area, the spare area can not be addressed by the user and is used to replace any defective blocks. 当在记录期间发现有缺陷块时,在备用记录区域中而不是在缺陷块中进行记录。 When during recording a defective block is found, instead of in the defective block is recorded in the spare recording area.

将数据分组记录在备用记录区域的逻辑块后,继续将下面的数据分组记录在缺陷块后面的逻辑块中。 After the data packets recorded in the spare recording area of ​​the logical block, data packets continue to be recorded following the defective block in the following logical blocks. 因此,这样的替换需要记录头的两次跳转,在读取信息时同样需要记录头的两次跳转。 Thus, such a replacement requires two jumps of the recording head, the recording information is read also requires two hops head.

使读写头从正常记录区域到备用记录区域的跳转和跳回花费了相对较多的时间并降低了信息的平均传输速率。 So that the head from the normal recording area to the spare recording area and jump jump back takes relatively more time and reduce the average transmission rate information. 这在要求很高传输速率的情形中是特别不期望的,例如在实时记录音频和/或视频信号中。 This is particularly undesirable in the case of demanding a transmission rate of, for example, real-time recording of audio and / or video signals.

为此,建议不为单个的被损坏块跳转到备用记录区域和跳回,而是在发现缺陷块时,在备用区域记录包括多个逻辑块的文件区段。 For this reason, it is recommended not to be damaged as a single block and jumps to spare recording area jump back, but found defective block, recording a file portion comprising a plurality of logic blocks in the spare area. Present

4在这种跳转在时间上不是紧接着另一个跳转发生,而是在两次之间有较长的时间间隔。 4 in which the time is not immediately jump to another branch occurs, but a longer time interval between the two. 于是在一个不包括两次跳转的时间间隔内平均传输速率较高。 Thus in an interval comprising two hops higher average transmission rate. 不过,造成的结果是备用记录区域被迅速填满,然后记录在备用记录区域的大部分数据分组错误地占用了备用记录区域的空间,因为正常记录区域中这些和数据分组相对应的逻辑块不是有缺陷的。 However, the resulting spare recording area is filled rapidly, and most of the data recorded in the spare recording area packet error record to the space occupied by the spare area, such as a normal recording area and the data packets corresponding to the logical block is not Defective. 因此,跳转次数的减少伴随着对备用记录区域相对低效的使用, Thus, reducing the number of jumps is accompanied by relatively inefficient use of the spare recording area,

以及备用记录区域蜂皮更加迅速地填满; 一旦备用记录区域#:填满,该 Paper wasp and spare recording area more quickly fill; once the spare recording area #: full the

盘就不再被用于进一步的记录。 Plate no longer be used for further recording. 相反的是,这意味着针对其进行了替换记录的文件区段的数目比较小。 Conversely, this means that the number of records for which were to replace the file sector is relatively small. 发明内容 SUMMARY

本发明的一个目的是为上述问题提供一个解决方案。 An object of the present invention is to provide a solution to the above problems. 按照本发明的一个重要方面,替换记录在空闲记录区域,即还没有被使用的可自由访问的、可寻址的区域中进行。 According to an important aspect of the present invention, the replacement recording in the free recording area, i.e. freely accessible yet be used, for addressable region. 这个区域大得足够用以记录具有连续的以百计的长度的文件区段。 This area is large enough to record a continuous length of hundreds to a file portion. 在记录之前,分配管 Prior to recording, the dispensing tube

理器将空闲记录区域的一个特定部分作为替换区域保留。 A processor idle particular portion of the recording area reserved as a replacement zone. 这样的保留意味着, 一方面,分配管理器将不会使用这个空闲记录区域的保留部分中的地址去记录。 Such retention means, on the one hand, the allocation manager will not use this address to record the reserved portion of the free recording area. 如果在记录期间发现缺陷块,写记录头就跳转到空闲记录区域的保留替换区域中的适当地址,例如替换区域中的第一空闲地址,以及在该替换区域进行替换记录。 If a defective block found during the recording, the write head jumps to a suitable address of the reserved replacement zone of the free recording area, for example, a first replacement area in the free address, and the replacement recording in the replacement region. 在将文件区段记录在这个替换区域之后,写记录头返回到正常记录区域。 After the file is recorded in the replacement sector area, the write head returns to normal recording area.

在记录会话完成后,通知分配管理器替换区域中的哪些地址已被用于替换以及替换地址与原始地址的对应关系。 After the recording session is completed, the replacement allocation manager notification address area which has been used to replace the corresponding relationship between the address and the replacement of the original address. 于是分配管理器就知道空闲区域中的哪些地址不再空闲以及原始分配地址中的哪些还没有被使用而因此事实上依然是空闲的。 So allocation manager knows which addresses are no longer free area which has not been idle, and use the original allocation of addresses and therefore the fact remains idle.

可选地,在记录会话期间这个信息可能已经被传递给分配管理器,其结果是,如果必需,分配管理器可以在记录过程期间在正常存取空间中保留额外的空间,例如在发生大量错误时。 Alternatively, during the recording session information may have been transferred to the allocation manager, a result which, if necessary, the allocation manager can be reserved additional space in the normally accessible space during the recording process, for example, a large number of errors occur Time.

对本领域的技术人员来说,显然本发明的范围并不局限于在上文中所描述的实例,而是在不脱离附加的权利要求中所定义的本发明的范围的情况下,可能对其进行各种变化和修改。 Those skilled in the art, it is clear that the scope of the present invention is not limited to the examples described hereinbefore, but the present invention without departing from the scope of the appended claims, as defined, may be various changes and modifications. 例如,如果在测试过程中只检查预先确定的测试轨道,本发明就已经是优选的,即使该测试过程并不基于跟踪信号的使用,虽然这是优选的。 For example, if only checks a predetermined test track during the test, the present invention has a preferred, even if the test procedure is not based on the use of the tracking signal, although this is preferred. 盘2可以是磁盘但本发明特别打算用于光盘记录。 2 may be a magnetic disc but the present invention is particularly intended for the optical disk recording. 盘2包含多个彼此同心的记录轨道3,该轨道3在下文中被假定为单个圆形轨道,但该轨道3也有可能表现为一个连续的螺旋形轨道。 2 comprises a plurality of disc recording tracks 3 concentric with each other, the rail 3 is assumed to be a single circular tracks hereinafter but the track 3 may also appear as a continuous spiral track. 正如本身已知的,设备1具有一个光学写/读头10和一个转盘,为了简明没有显示转盘,该转盘朝向记录头10,盘2可以;故定位在该转盘上,以及通过转盘盘2可以进^f亍相对记录头10的旋转运动而使轨道3能被记录头IO扫描到。 As known per se, the apparatus 1 has an optical write / read head 10 and a turntable, not shown for simplicity carousel that the recording head 10 toward the disc 2 may be; so positioned on the turntable, and the turntable the disc 2 can ^ f right foot forward relative to the rotational movement of the recording head 10 of the rail 3 can scan the recording head to IO. 记录设备1还包括一些用于在盘2的径向方向上移动记录头10的装置,因其本身是已知的,故为了简明没有显示,这样使得盘2的不同轨道3可被写/读头10访问。 The recording apparatus 1 also includes means for moving the recording head 10 in the radial direction of the disk 2, and because it is known per se, and therefore not shown for simplicity, such that different tracks 3 of the disc 2 may be written / read head 10 access. 众所周知,信息是通过来自记录头10的激光束11写到轨道3上的。 Is well known, information is generated by a laser beam from the recording head 10 on the track 11 written 3.

写的过程由功能单元20来控制,该单元在下文中被称作为写控制单元。 The write process is controlled by a functional unit 20, the cell is referred to as the write control unit hereinafter. 这样的写控制单元20就其本身而言是已知的,因此不再作进一步描述。 Such a write control unit 20 is known per se and therefore will not be further described. 应当指出的只有,写控制单元20适合于以这样一种方式来控制写/读头10相对盘2的位置,即通过控制盘2的转盘以及写记录头10的定位装置来在盘2的要求位置进行写过程。 It should be noted that only, write requests to the control unit 20 is adapted in such a way to control the write / read head 10 relative to the position of the disc 2, i.e., the control panel 2 by the turntable positioning means and writing to the recording head 10 of the disc 2 position of the writing process. 此外,写控制单元20 依赖要记录的输入信号S来控制激光束11的亮度。 Further, the write control unit 20 dependent on the input signal S to be recorded to control the brightness of the laser beam 11. 写控制单元20的控制功能图示化地表示为图1中的连接22。 Write control function of the control unit 20 illustrated in FIG 1 showing the connection 22.

记录设备1还包括一个功能单元30,在下文中被称作分配管理器。 The recording apparatus 1 further comprises a functional unit 30, referred to hereinafter allocation manager. 这样一个分配管理器30其本身是已知的,因此不再作进一步描述。 Such an allocation manager 30 are known per se and therefore will not be further described. 应当指出的只有,分配管理器30适合于判定一个特定的记录会话或记录将发生在盘2的哪个部分。 It should be noted that only the allocation manager 30 is adapted to determining a particular recording session or recording will occur in which part of the disc 2. 当用户开始一个记录时,分配管理器30判定在相应的盘2上是否有足够的空间用于记录,以及如果情况是这样,则判定何处可得到这样的空间-分配管理器30通知写控制单元20 这个可用空间的起始位置,该空间被图示化表示为信号连接31。 When a user starts a recording the allocation manager 30 determines whether there is in the corresponding disc 2 for recording sufficient space, and if this is the case, where it is determined that this available Space - the allocation manager 30 notifies the write control 20 the starting position of this unit in the available space, the space is illustrated as a representation of a signal connection 31.

图2图示化表示了盘2的逻辑结构。 FIG 2 illustrates a logical representation of the structure of the disc 2. 记录轨道3 —起定义了盘2 的可记录区域40,该区域被显示为连续的条,在下文中也被称作记录区域。 Recording track 3 - defines the recordable area from 40 to 2, the area is shown as a continuous strip, hereinafter also referred to as the recording area.

盘2的记录区域40被划分成逻辑块45,每一个逻辑块有各自的预定地址。 The recording area 40 of the disc 2 is divided into logic blocks 45, each block having a respective predetermined logical address. 逻辑块45相应地址的值已经被记录在块45的预定地址域中。 Value 45 corresponding logical block address has been recorded in a predetermined address field 45 of the block. 因此将信息直接记录在和盘2上的给定地址相对应的给定位置是可能 Thus given address information is recorded directly on the disk 2 and corresponding to the given location is likely to

的,且将信息直接从和给定地址相对应的给定位置中读取同样也是可能的。 , And the information is read directly from the given address and corresponding to a given location is also possible. 块45具有一个逻辑块尺寸,该尺寸对所有块来说不必相等,一个逻辑块里可以写入的数据量被称为一个数据分组。 Logic block 45 having a block size which is not necessarily equal for all the blocks, the amount of data that can be written in a logical block is referred to as a data packet.

记录区域40包括的一个主要部分是所谓可寻址空间41,该地址空间可被用户访问以便记录信息,所述信息在本实例中是数字视频信号。 A major portion of the recording region 40 includes a so-called addressable space 41, the address space can be accessed by a user for recording information, the information is a digital video signal in the present example. 这个可寻址空间41因此将在下文中被称作用户区域。 This addressable space 41 will therefore be hereinafter referred to as user area.

盘2的记录区域40还包括备用区域42,该区域不可寻址,以及作为替换区域使用。 The recording area 40 of the disc 2 further includes a spare area 42, this area can not be addressed, and the use as a replacement area. 图2中没有显示用户区域41与备用区域42的相关存储容量的比例: 一般而言,备用区域42的大小只是用户区域41大小的百分之几。 2 is not shown in FIG. 41 related to the ratio of the storage capacity of the user area and the spare area 42: In general a few percent, the size of the spare area 42 is only the size of the user area 41.

盘2还包括预定区域43,该区域存储了涉及盘中内容的信息。 2 further comprising a predetermined region of the disc 43, which area stores information relating to the disc content. 这些信息可能涉及,例如,盘2上的文件数、文件的起始地址、文件的长度、文件名等。 This information may relate to, for example, the number of files on the disc 2, the length, the starting address of the file name of the file, the file and the like. 区域43在下文中将被称作管理区域。 Area 43 is referred to hereinafter in the management area.

在图2中,文件标有参考符号fl, f2, f3等。 In FIG. 2, the file marked with the reference symbols fl, f2, f3 and so on. 一般而言,文件占用多个块45,以致文件包括多个数据分组。 In general, files occupy a plurality of blocks 45, so that the file comprises a plurality of data packets. 用户区域45中已经被用于文件存储的那部分被称作占用的用户区域46或占用空间。 That part of the user area 45 has been used for file storage is referred to as occupied user area 46 or occupied space. 用户区域45 中未被使用的那部分依然空闲:在下文中这部分将被称作空闲用户区域或空闲空间47。 Unused portion of the user area 45 is still free: this part will hereinafter be referred to as the free user area or free space 47. 在可寻址区域41中,文件使用的块不必直接与另一块毗邻。 41 in the addressable area, block files need not be directly adjacent to one another. 文件可能包括多个段,每一个段可能包括多个块,这些段可能分散在可寻址区域41中。 File may include a plurality of segments, each segment may include a plurality of blocks, which segments may be scattered in the addressable area 41. 因此空闲空间由具有尚未使用的块的多个段组成。 Thus the free space having a plurality of segments consists of unused blocks. 这些地址被保存在管理空间43中。 These addresses are stored in the management space 43. 为了简化,文件被表示成单个连续的区域。 For simplicity, the files are represented as a single continuous region.

当盘2被装进记录设备时,分配管理器30通过连接31命令写控制单元20来读取管理区域43并将这样读取的信息通过连接31传递到分配管理器30。 Information when the disc 2 is loaded into recording apparatus the allocation manager 30 via the control connection 31 commands the write unit 20 reads the management area 43 and the thus read is transferred through the connector 31 to the allocation manager 30. 分配管理器30将读取的信息存储在相关的存储器32 中。 The allocation manager 30 stores the information read in the associated memory 32. 分配管理器30现在知道盘2的用户区域41中哪个部分已^皮在前记录的文件fl, f2等占用,以及因此成为占用的用户区域46或占用空间。 The allocation manager 30 now knows the disk 2 which part of the user area 41 has front transdermal ^ fl record file, f2 occupy the like, and thus becomes occupied user area 46 or occupied space. 作为结果,分配管理器30也知道用户区域41中哪个部分依然空闲,并因此而成为空闲用户区域或空闲空间47。 As a result, the allocation manager 30 also knows which part of the user area 41 is still free, and thus become free user area or free space 47.

当分配管理器30接收到一个新的写命令时,分配管理器30在相关存储器32中检查用户区域41的哪个部分是空闲的,并通过通信线路31发送这个空闲空间中的起始地址和结束地址到写控制单元20。 When the allocation manager 30 receives a new write command the allocation manager 30 checks in the associated memory 32 which part of the user area 41 is free, and transmitting the start address of the free space and the end 31 through a communication line address to the write control unit 20. 分配管理器30还将这个数据存储在存储器32中,标志由所迷起始地址和结束地址定义的用户区域41的这个部分不再属于空闲用户区域47 而是属于占用的用户区域46。 The allocation manager 30 also stores this data in the memory 32, the user flag area defined by the fan start address and end address no longer belongs to the portion 41 of the free user area 47 but to the occupied user area 46. 写控制单元20为将,史记录的信号S控制记录过程,该记录开始于从分配管理器30接收的起始地址,是以通常方式进行的。 The write control unit 20, a control signal S history recording process of recording, the recording begins at the start address received from the allocation manager 30, is performed in the usual manner. 当记录过程已经完成后,写控制单元20通过通信线路31 向分配管理器30报告,在此之后,分配管理器30命令写控制单元20 更新盘2的管理区域43中的数据。 When the recording process has been completed, the write control unit 203 130 reports to the allocation manager through the communication line, after which the allocation manager 30 commands the write control unit 20 updates the disc management area 2 data 43.

用户区域41可能包含缺陷块45*。 User area 41 may contain defective blocks 45 *. 这样特定缺陷块45*的存在事先不为分配管理器30知晓是可能的,因此这些缺陷块45*被正常地用于分配。 There is a certain defective blocks 45 * is not previously known to the allocation manager 30 are possible, so these defective blocks 45 * are normally used for allocation. 不过在记录前分配管理器30知道哪些块由于存在缺陷而不能使用也是可能的。 However, before the recording the allocation manager 30 knows which blocks are unusable due to defects is possible. 在传统的方式中,这些块45*依然被用于分配。 In the conventional manner these blocks 45 * are still used for allocation. 假设写控制单元20自己选择了可供选择的一个位置。 Write control unit 20 assume that he chose a location to choose from. 如果在写期间,写记录头10到达一个缺陷块45*,则写控制单元20应该将写记录头10移动到一个可供选择的块以及将已经写入相关缺陷块45*的数据分组记录到该可供选择的块中。 If during data writing, the write head 10 reaches a defective block 45 *, the write control unit 20 should move the write head 10 to an alternative block and the defective block has been written to the relevant packets recorded 45 * the alternative block. 在将数据分组记录在另一个可供选择的块中之后,写控制单元20命令写记录头10以传统方式返回到用户区域41。 After the data packet is recorded in another alternative block the write control unit 20 commands the write head 10 in a conventional manner to return to the user area 41.

这样的一个可供选择的块也被称作替换块45',且将数据分组记录在替换块45'也被称作替换记录。 Such an alternative block is also called a replacement block 45 ', and the packet data is recorded in a replacement block 45' is also called a replacement recording.

传统地,在备用区域42中选择可供选择的块45'。 Conventionally, an alternative block selection in the spare area 4245 '.

由于写记录头IO的来回移动损失了大量时间,所以这样造成的结果是:这样一种传统的写过程不太适合于实时的视频信号的处理。 Because of the write head moves back and forth IO lost a lot of time, so this result is due to: a traditional writing process is not suitable for real-time processing of video signals. 本发明建议减少写记录头IO的跳转移动次数并且增加连续跳转移动之间的时间,其中当写记录头IO到达一个缺陷块45*且随之必须跳转到替换块45'时,替换记录不是只对要被写入缺陷块的单个数据分组进行而是在跳转回去之前还将大量的后续数据分组写入该替换块45\因此被写入替换块45'的后续数椐分组数可以是100或更多。 The present invention proposes to reduce the number of hops IO write head movement and to increase the time between successive jump move, wherein when the IO write head reaches a defective block 45 * and subsequently must jump to a replacement block 45 ', the replacement the number of records noted in the number of subsequent packets to be written not only for a single data packet defective block but before jumping back also a large number of subsequent data packets written into the replacement blocks 45 \ replacement block 45 is thus written apos It may be 100 or more. 事实上,错误经常是成簇发生的。 In fact, errors often occur in clusters. 通过接受多个数据分组而减少了跳转次数。 By receiving a plurality of data packets to reduce the number of hops. 这样的被写入替换块45'的连续数据分組的序列也被称作文件区段。 Such replacement is written in block 45 'of a sequence of consecutive data packets is called file section.

预定的保留区域42相对较小。 Predetermined reserved area 42 is relatively small. 特别地,这个备用区域42已经被设计成容量大约是整个盘容量的3%,因此如果缺陷块不超过3%,就可以为所有缺陷块45*提供可供逸择的写容量。 In particular, this spare area 42 has been designed to be about 3% of the total capacity of the disk capacity, so if a defective block not exceed 3%, all defects that can provide write block 45 * Yi selection of available capacity. 在传统写过程中,实际上这是充足的,因为在那种情况下,只有备用区域42中的一个单个替换块45'被用户区域41中的每一个缺陷块45*所使用。 In traditional writing process, in fact, this is sufficient, because in that case, only a single spare area 42 of the replacement block 45 'is a defect of each of the user area 41 * 45 blocks are used. 不过,如果大小为100或更多数据分組的文件区段同时被写入备用区域42,则不可避免的是:也需要大量备用区域42中的替换块45'作为可供选择的记录区域用于用户区域41的无缺陷块45。 However, if the size is 100 or more data packets are written to the file sector while the spare area 42, it is inevitable that: also requires a lot of spare area 42 replacement block 45 'as an alternative recording area for defect-free user area 41 of the block 45. 这意味着备用区域42被迅速填满, 以及甚至在用户区域41中缺陷块45*的数目远小于3%时,它可能已经被填满。 This means that the spare area 42 is filled rapidly, and even in the user area 41 is defective when the number of blocks 45 * is much less than 3%, it may have been filled. 当备用区域42填满时,盘2不能再用于进一步的记录。 When the spare area 42 has been filled, the disc 2 can no longer be used for further recording.

本发明同样提供对这个问题的解决方案。 The present invention also provides a solution to this problem.

为此,依照本发明,分配管理器30适合于在空闲用户区域保留两个不同的区域用于记录,保留第一区域用于正常记录,保留第二区域用于替换记录。 To this end, according to the present invention, the allocation manager 30 is adapted to remain in the free user area for recording two different areas, a first area reserved for normal recording, the second reserved area for replacement recording. 分配管理器30将这些区域通知给写控制单元20。 The allocation manager 30 informs the write control these regions unit 20. 写控制单元2G适合于在第一区域执4于正常记录,在发现缺陷块45*时,在第二区域执行文件分段的替换记录。 2G write control unit 4 is adapted to perform normal recording in the first area, the defective block 45 * is found, the execution file of the second segment of the replacement recording area.

如图3所示,为了这个目的,分配管理器30适合于在空闲用户区域47中指定一个写起始地址WSA和一个写结束地址WEA,这些地址为正常记录保留一个区域NW,以及在空闲用户区域47中还指定一个替换起始地址RSA和一个替换结束地址RM,这些地址为替换记录保留一个区域RW。 3, for this purpose, the allocation manager 30 is adapted to be specified in the free user area 47 a write start address WSA and a write end address WEA, these addresses are reserved zone NW of a normal recording, and the idle users region 47 also specify a replacement start address RSA and a replacement end address RM, these addresses reserved a replacement recording area RW. 图3显示了为正常记录保留的区域NW位于空闲用户区域47 的开端部分而为替换记录保留的区域RW位于空闲用户区域47的结尾部分。 Figure 3 shows the beginning part of the free user area is located in the area NW reserved for normal recording and located at the end portion 47 of the free user area 47 is an area RW reserved for replacement recording. 事实上,空闲用户区域包括多个分散在整个可寻址空间上的非连接区域。 In fact, the free user area including a plurality of non-connected regions dispersed over the entire addressable space. 因此,为替换记录保留的那个区域RW与为正常记录保留的区域NW s比邻也是可能的。 Therefore, the area RW reserved for replacement recording is reserved for the normal recording area NW s neighbor is also possible.

分配管理器30适合于将这些地址传送给写控制单元20,控制单元进而又适合于保证在空闲用户区域47内为正常记录保留的区域鼎中以传统方式进行信息流的记录。 The allocation manager 30 is adapted to transmit these addresses to the write control unit 20, the control unit is adapted to turn the tripod guaranteed area within the free user area 47 reserved for normal recording is recorded in a conventional manner the flow of information. 不过,写控制单元20适合于保证在发现缺陷块4"时,写记录头10跳转到在空闲用户区域47内替换区城RW中的一个位置,以便在该位置进行文件区段的替换记录,以及随后使得写记录头10跳转回到空闲用户区域47内为正常记录保留的区域丽。显而易见的是替换记录以这种方式进行而没有上文中描述的缺点。因此,特别地,没有使用备用区域42。 However, the write control unit 20 is adapted to ensure that a defective block found when the 4 ", the write head 10 jumps to a location in a city zone RW within the free user area 47 in the alternative, the replacement recording for a file portion in this position and subsequently write head 10 so that a jump back to the area within the free user area 47 Li reserved for normal recording is evident that in this way replacement recording is performed without the drawbacks described above. Thus, in particular, do not use spare area 42.

通常,写控制单元20在记录过程已结束时,向分配管理器30报告,据此,分配管理器30命令写控制单元20更新盘2的管理区域43 中的数据。 Typically, writing when the recording process has ended, the allocation manager 30 reports to the control unit 20, whereby the allocation manager 30 commands the write control unit 20 updates the management data area of ​​the disk 43 2. 分配管理器30将为替换记录保留的区域RW中的地址添加到管理区域43中的该管理数据上。 RW region allocation manager 30 for replacement recording of the reserved address is added to the management data in the management area 43. 没有使用过的带有缺陷的地址被留 Not used addresses are left with a defective

在空闲用户区域中。 In the free user area. 将这些地址添加到不可靠地址列表中也是有可能的。 Add these addresses to the address list is unreliable possible. 然后在随后的记录过程中,分配管理器30能够决定不将这些地址 Then during a subsequent recording the allocation manager 30 can decide not to address these

用于分配。 For assignment. 这在重新分配期间,避免了时间损失。 During this re-allocation, to avoid loss of time.

因此,用户区域41的被占用空间46现在包括被正常记录所占用的一部分46W、已经在区域NW中4吏用的块和已经在区域RW中使用的块。 Thus, the space occupied user area 41 now comprises a part 46W of 46, 4 have been used in the area NW officials block and the block has been used in the area RW are occupied by normal recording. 分配管理器30将其写入存储器32,以及在完成记录会话时,它将这些信息记录在盘上管理区域43中的内容表中。 The allocation manager 30 writes the memory 32, and upon completion of the recording session, it records the information in the table of contents on the disk management area 43.

当下一次盘2被装入设备1时,执行相同的过程:分配管理器30 识别出已经使用过的地址。 The next time when the disc 2 into the device 1, the same procedure: the allocation manager 30 recognizes the addresses that have been used. 从这个信息,它可以得知剩余哪个空闲用户区域。 From this information, it can know which remaining free user area. 这个空闲区域的一部分被保留用于替换记录,这个区域不必与前面记录过程中的区域是同一部分。 Part of the free area is reserved for replacement recording, the recording region preceding the region need not be the same part of the process.

正常情况下,空闲用户区域47中的替换区域RW的大小大于备用区域42,并且大得足够处理正常条件下发生的替换记录的数量。 Under normal circumstances, the free user area size of the replacement area in the RW 47 is greater than the spare area 42, and the number of the replacement recording process occurs under normal conditions is large enough.

如果在记录期间由于盘变满而使得剩余的空闲用户空间变小,但在替换空间中尚有余地,则分配管理器30可以通过将这一情况通知给写控制单元20而减少替换空间。 If the disc becomes full during recording because the user so that the remaining free space becomes smaller, but there is room in the replacement space, the allocation manager 30 may be notified of this case to the write control unit 20 to reduce the replacement space. 这样,整个盘可被用来存储。 Thus, the entire disc can be used to store. 在记录会话期间写控制单元有可能将替换区域RW中剩余的未使用部分的信息提供给分配管理器30,作为结果,如果替换记录的数目相当大且甚至在记录会话完成以前替换区域就因此要变满,则分配管理器30能扩充替换区域RW。 Write control means during a recording session is possible to replace the information of the unused portion of the area RW remaining is supplied to the allocation manager 30, as a result, if the number of replacement recording quite large and even prior to the completion replacement area in a recording session can therefore becomes full, the allocation manager 30 can replace the expansion area RW.

一旦分配管理器30已经保留了空闲用户区域47的一部分,则分配管理器30将不再认为这部分区域是可以被正常记录所自由使用。 Once the allocation manager 30 has retained a portion of the free user area 47, the allocation manager 30 will no longer consider this part region can be freely used for normal recording. 由本发明提出的方法有一些主要的优点。 The method proposed by the present invention has some major advantages. 在记录会话或记录期间,空闲空间中替换区域的大小可以动态变化。 During the recording session or recording, the free space size of the replacement area may change dynamically. 作为保留的替换区域 Alternatively reserved area

的结果,这并不引起任何播放时间损失。 The result, which does not cause any loss of playing time. 而且,即使当多于3%的记录区域有缺陷时,该盘依然可使用。 Moreover, even when more than 3% of the recording area is defective, the disc can still be used. 理论上,甚至在近乎100%的存储空间有缺陷时,该盘依然可使用,但是由于更多的存储空间有缺陷和需要更多的替换空间,使得剩余播放时间相应减少(适度恶化)。 Theoretically, even when nearly 100% of the storage space is defective, the disc can still be used, but as more storage space is defective and more replacement space needed, so that a corresponding reduction in the remaining playing time (moderate deterioration). 这是和传统方法比较而言,在传统方法中,当出现大于3。 This is a conventional method and comparison, in the conventional method, when there is greater than 3. /fl的缺陷时, 一个 Defect / fl, and a

盘就不再能用了。 The disk will no longer be used.

总之,因此本发明特别提供了一种用来在具有记录区域40的DVR 盘上记录实时的视频信号的方法,记录区域40包括管理区域43、备用区域42和用户区域41。 In summary, the present invention thus especially provides a method for recording real-time video signals on a DVR disc having a recording region 40, the recording region 40 43 includes a management area, the spare area 42 and a user area 41. 在用户区域的空闲部分47的第一预留区域NW 的块45中进行正常记录。 Normal recording block 45 in the free user area NW reserved area of ​​the first portion 47. 在记录过程期间如果遇到缺陷块45*,则在用户区域的空闲部分47的第二预留区域RW中进行多个块大小的文件区段的替换记录,在此之后,继续在笫一预留区域鼎中进行正常记录。 If you encounter a defective block 45 *, the replacement recording of a file segment in the plurality of block sizes of the free user area RW reserved region of the second portion 47 during the recording process, after this, to continue in a pre-Zi Ding aside the normal recording area. 一方面,这样减少了跳转次数并限制了在一段短时间内由于替换记录引起的跳转次数,另一方面,非常有效地使用了该盘的存储容量. In one aspect, this reduces the number of jumps and limits the number of hops in a short period of time due to the replacement recording due to, on the other hand, very efficient use of storage capacity of the disk.

对本领域的技术人员来说,显然本发明的范围并不局限于在上文中所描述的实例,而是在不脱离附加的权利要求中所定义的本发明的范围的情况下,可能对其进行各种变化和修改。 Those skilled in the art, it is clear that the scope of the present invention is not limited to the examples described hereinbefore, but the present invention without departing from the scope of the appended claims, as defined, may be various changes and modifications.
